Fig. 2 is the structural representation of local antenna and the minor matters that are arranged on circuit board according to an embodiment of the invention.
Detailed description of the invention
Hereinafter, with reference to the accompanying drawings to embodiments of the invention are described in detail. However, it is possible to implement the present invention in many different forms, and the present invention should not be construed as limited to the specific embodiment set forth here. On the contrary, it is provided that these embodiments are to explain principles of the invention and practical application thereof, thus others skilled in the art are it will be appreciated that various embodiments of the present invention and be suitable for the various amendments of specific intended application. Identical label can be used to represent identical element in entire disclosure and accompanying drawing.
Fig. 1 is the front view of antenna structure according to an embodiment of the invention. Fig. 2 is the structural representation according to embodiments of the invention local antenna and the minor matters that are arranged on circuit board. It should be noted that the antenna structure of the present invention can be used in the mobile terminal such as smart mobile phone, panel computer.
Seeing figures.1.and.2, antenna structure includes according to an embodiment of the invention: antenna holder 10 and be arranged at the antenna 20 on antenna holder 10. Antenna 20 includes spaced first antenna main body the 21, second antenna body 22, the first antenna grounding leg 23 that one end by first antenna main body 21 extends to form, one end of the second antenna body 22 the second antenna ground foot 24 extended to form and antenna feed foot 25. Wherein, described first antenna main body 21 primarily serves coupling, and feed effect mainly occurs described second antenna body 22.
In the present embodiment, first antenna grounding leg 23 and the second antenna ground foot 24, antenna feed foot 25 are separately positioned, and the second antenna ground foot 24 and antenna feed foot 25 connect and arrange; But the present invention is not restricted to this. Additionally, antenna feed foot 25 is between first antenna grounding leg 23 and the second antenna ground foot 24, but the present invention is not restricted to this.
In the present embodiment, it is intended that on antenna holder 10, the side at first antenna main body 21 and the second antenna body 22 place is the first side 101, the namely front of described antenna holder 10; Then described first antenna grounding leg the 23, second antenna ground foot 24 and antenna feed foot 25 are arranged on the back side of first antenna main body 21 and the second antenna body 22.Here, drawn minor matters 241 by the second independent antenna ground foot 24 and extended on circuit board 11.
It should be noted that in the present embodiment, between first antenna main body the 21, second antenna body 22 and the minor matters 241 extended on circuit board, there is certain antenna head room. When the head room of first antenna main body the 21, second antenna body 22 reduces, first antenna main body the 21, second antenna body 22 and minor matters spacing are pressed close to, and form coupling effect.
Being the second antenna feed foot 24 being connected with the second antenna body 22 due to what draw minor matters 241, the second antenna body 22 primarily serves feed effect.
